. thel pinion plate The 'rack 47 normally projects through f ithe .ca'sing plate slot 1,2 asshown in Fig. 1

' .the rack 47 inwardly, thus tiltin 'tooth 45 being broug of the ratchet wheel and has al push button 54 secured to the "top thereof. -Ini operating the'device, an

inward impulse exerted upon the push button 54 by thedi'nger of the operator forces the pinion plate 31 upon the shaft 26 an the pawl ht into engagement with one "of the teeth 30, the star wheel 27 isl thereby revolved bringing the'engaging end 28 otone of the arms thereof into engagement with the coni tact arm 22 for depressing the same against positions of the contactvarm I21, the relative change of the contact arm and star wheel beingv from the position shown in Fig. 1 to that of Fig. 4; Upon such a positioning of the star whee as just described, the spring 46 will engage one of the teeth of the ratchet wheel 30 retaining'the star wheel so positioned, while a release of the push button 54 allows'the spring 34 to revolve the pinion plate and automatically return both the plate and its rack 47 toy their normal position. 'A succeeding similar actuation of the push button-rack and pinion tu res.

plate will result in turning the star wheel a one-eighth -turn which will release its engaging arm 27 from the contact arm 22, allowing the contact arms to automatically separate, it being understood that the spring 46'then engages a succeeding tooth of the ratchet wheel.

A readily operable snap provided in which each alternate actuation thereof makes and breaks the electrical connections between the terminal contacts'of the switch.

While the Jform of Vthe inventionherein shown and described is what 'is believed toA be the preferred embodiment thereof, it is swit'cli is thus f sol nevertheless to be understood that minor i changes 'may be made witho'ut departing from the spirit and scope of the invention as claimed. y What is claimed as new is -Asnap switch comprising a casing, a

v'iframe mounted therein, a shaft journaled 1n the frame, normally separated terminalv contacts between the said shaft and frame,

a star wheel journaled uponthe said shaft and having its arms provided `with a path of movement in the plane of the said contacts, a ratchet wheel connected to the said star wheel, a pinion plate journaled upon the said shaft, an engaging pawl for the saidratchet wheel pivoted to the said plate,-

the said pawl being U-shaped and having opposite notches ion plate being its base portion,

provided with a notch in a looped curved wire spring therein, and the said pin having a central portion ,secured within the said pinion plate notch and with its tree ends engaging the said pawl notches and -a shiftable actuating rack for the said pinion plate. A l
